Two teams of scientists, one at the University of Texas and another led by Mihai Polceanu from Romania, have managed to create game playing artificial intelligences that were able to fool a panel of judges that they were human, based on their actions in Unreal Tournament 2004.
Testing was done via a match of the multiplayer shooter which also included a judge gun that allowed opponents to be tagged as either computers or humans, with the humanness rating going above 50 percent for the two teams mentioned above.
Risto Miikkulainen, who is a professor at the University of Texas, stated, “When this 'Turing test for game bots' competition was started, the goal was 50 per cent humanness. It took us five years to get there, but that level was finally reached last week.”
Jacob Schrum, a doctoral student that was also part of the team, added, “People tend to tenaciously pursue specific opponents without regard for optimality. When humans have a grudge, they'll chase after an enemy even when it's not in their interests. We can mimic that behavior.”
